Why Source Code is Always Text
summary
Argues that source code stays as plain text because it hits the right abstraction level for debugging, tooling and collaboration: historical quirks like the 80-character punch card legacy (card format from 1928) explain limits; attempts to replace text — HyperCard, Visual Basic, Interface Builder, spreadsheets — deliver binaries or visual stacks but produce leaky layers; GWT (Java→JavaScript) creates a GWT leaky-abstraction needing multiple languages; Go’s formatter enforced formatting at compile time (Go formatter enforces formatting), proving automated text tooling scales. AI accelerates generation but still requires human-level debugging.
